LEWIS B. WHITE AND LEONARD HENDERSON, OF MIDDLEBURG, N. O.

SMOKE AND DU ST ARRESTER FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 225,448, dated March 9, 1880..

Application filed August 16, 1879. I

,To all whom it may concern:

Be it known that we, LEwIs B. WHITE and LEONARD HENDERSON, of Middleburg, in the county of Warren and State of North Carolina, have invented a new and Improved Smoke and Dust Arrester for Railway-Oars; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this'specification, in Which- Figure l is a side elevation of a train with the last car in vertical section. Fig.2 is an enlarged vertical section of the lower portion of said rear car. Fig. 3 is an inverted plan view of the underneath side of the car-body, and a plan view of the trucks detached.

The object of our invention is to dispose of the dust from the railroad-track and the smoke from the smoke-stack in such a manner as to relieve railroad travel of this disagreeable incident.

To this end our invention consists in inclosing the trucks of the cars in a housing having doors at the ends, which housings communicate with a pipe extending through the entire train, and through which pipe the air and dust from the wheels is drawn by a fan 10- cat'ed in the rear car, and through which pipe also the smoke may be drawn from a hood located above the smoke-stackof the locomotive, as hereinafter more fully described.

In the drawings, A represents the locomotive; B, one of the middle cars, and O the end car, of a train provided with our improvement. D are housings, which completely inclose the trucks of the car and extend down to a position close to the rails. These housings have hinged side doors, D, through which access may be had to the wheels for the purpose of testing and oiling the same, and end doors, D Of these end doors, those which are the front ones of each truck are raised when the train is moving, as shown, so as'to allow the housing to catch and retain the dust which is raised by the train.

In disposing of the dust the housing of each truck of the middle cars communicates with the main pipe E through the flexible branches at a.

For giving a positive draft to the air in the said pipe E we locate between the two floors of the last car a horizontal radial-bladed fan, F, run through bevel-gear F, shaft F and pulley F by a chain-belt, G, and chain-pulley H on one of the axles of the car.

The continuous pipe E is connected between the cars by any suit-able flexible pipes, and the said pipe E'enters the fan near the center and leaves it at the periphery, as shown in Ijig. 3.

For adapting this lastcar to be run in the opposite direction without being turned around,

a duplicate inlet and outlet pipe, E, is made to connect with the fan-chamber in a manner reverse to the pipe E. These two pipes E and E are at this point suitably provided with valves to properly control the exhaust. To exhaust the air from the housings of this rear car separate branch pipes b b are made to coneither have 'a separate extension throughout the train to the fan, or be connected with the main pipe E.

Instead of using a housing for completely I inclosing the trucks of the car, we may, as a modification of our invention, employ at each v truck a funnel or scoop shaped hood, similarto that employed beneath the locomotive.

In more clearly distinguishing our invention, we would state that we are aware that it is not new to employ a series of deflectors or cur-w tains extending down from the sides of the car to a position near the track with a view to concentrating the draft beneath the train and retaining the dust there. Our invention differs from these in that the dust is drawn off independently from each truck, as fast as it rises, by a separate continuous pipe and fan.

We do not, furthermore, claim drawing ,the smoke and cinders from the locomotive smokestack into a hooded pipe bymeans of a fan, as this has been heretofore done; but we propose to employ this feature in connection with our peculiar devices.

and provided with end and side doors, as described.

3. The combination of the fan F,pipeE,and housings D with the pipe I and hooded scoop 15 I, located beneath the locomotive.
